“…In most bitumen as well as in opetroleum, the ratio V/Ni <1 shows that they are of tertiary age. Chibrevi and Mirzaani bitumens with a V/Ni ratio> 1 indicate that they belong to more ancient Paleozoic type [17].…”

Manifestations of natural bitumen are recorded in almost all regions of Georgia. The bitumen of Kari Crossing, Natanebi, Chibrevi, Baida, Polpoy-Teibi, Mirzaani and Kila-Kupra were studied. The main aromatic structures contained in organic extracts obtained from bitumen under investigation are identified, and physical and chemical characteristics, elemental composition and distribution of microelements in these organic extracts are determined. The study of microelements distribution showed that bitumen of the Kari Crossing and the Baida 2, in which the ratio V/Ni is less than 1 stratigraphically belong to the third-generation bitumen, and the Chibrevi and Mirzaani bitumen with the ratio V/Ni >1 is of older origin and belongs to Paleozoic period. By content of oils, tars and asphaltes the bitumen under investigation belong to the asphalt type bitumen.
